3.Babban tsayi da tsayin buɗewa da lokacin rufewa.Buɗewar buɗewa da rufewa na ƙofar yana ƙaruwa, kuma ana aiwatar da raguwar saurin ta hanyar dunƙulewa.
4. Lamarin guduma na ruwa ba shi da sauƙin faruwa.Dalili kuwa shine lokacin rufewa yana da tsawo.
5. Matsakaici na iya gudana a kowane bangare na famfo, kuma shigarwa ya dace.Ƙofar bawul tashar ruwa famfo ne musamman.
6. Tsawon tsari (nisa tsakanin fuskoki biyu masu haɗawa na harsashi) ƙananan ne.
7. The sealing surface ne mai sauki sa.Lokacin da buɗewa da rufewa suka shafi, saman hatimi biyu na farantin ƙofar da wurin zama na bawul za su shafa su zamewa juna.A karkashin aikin matsa lamba na matsakaici, yana da sauƙi don haifar da abrasion da lalacewa, wanda ke rinjayar aikin rufewa da dukan rayuwar sabis.
8. Farashin ya fi tsada.Alamar rufewa ta lamba ta fi rikitarwa don sarrafawa, musamman madaidaicin saman kujerar ƙofar ba ta da sauƙin sarrafawa
2.Globe Valve
Bawul ɗin globe bawul ɗin rufaffiyar kewayawa ne wanda ke amfani da diski (ɓangaren rufewa na globe valve ana kiran diski) don motsawa tare da tsakiyar tashar tashar wurin diski (wurin bawul) don sarrafa buɗewa da rufewa. bututun.Bawuloli na Globe gabaɗaya sun dace don jigilar ruwa da kafofin watsa labarai na gaseous ƙarƙashin matsi daban-daban da yanayin zafi a cikin ƙayyadadden kewayon kewayon, amma ba su dace da jigilar ruwa mai ɗauke da tsayayyen hazo ko crystallization ba.A cikin ƙananan ƙananan bututun, za a iya amfani da bawul na tsayawa don daidaita ma'aunin matsakaici a cikin bututun.Saboda ƙayyadaddun tsari, ƙananan diamita na bawul ɗin duniya yana ƙasa da 250mm.Idan yana kan bututun mai matsakaicin matsakaita da saurin gudu, saman rufewarsa zai ƙare da sauri.Don haka, lokacin da ake buƙatar daidaita ƙimar kwarara, dole ne a yi amfani da bawul ɗin magudanar ruwa.
Siffofin:
1.Rashin lalacewa da abrasion na farfajiyar rufewa ba su da mahimmanci, don haka aikin ya fi dogara kuma rayuwar sabis yana da tsawo.
2. Yankin wurin rufewa yana da ƙananan, tsarin yana da sauƙi mai sauƙi, da kuma sa'o'i na mutum da ake bukata don kera shingen shinge da kayan da ke da daraja da ake bukata don zoben rufewa ba su da ƙasa da na ƙofar bawul.
3. Lokacin buɗewa da rufewa, bugun diski yana ƙarami, don haka tsayin bawul ɗin tsayawa yana ƙarami.Sauƙi don aiki.
4. Yin amfani da zaren don motsa diski, ba za a sami buɗewa da rufewa ba zato ba tsammani, kuma abin da ake kira "hammer water" ba zai iya faruwa ba cikin sauƙi.
5. Ƙarfin buɗewa da rufewa yana da girma, kuma buɗewa da rufewa yana da wahala.Lokacin rufewa, motsin motsi na diski yana gaba da jagorancin matsa lamba na matsakaici, kuma dole ne a shawo kan ƙarfin matsakaici, don haka budewa da rufewa yana da girma, wanda ke rinjayar aikace-aikacen manyan diamita na duniya bawuloli.
6. Babban juriya kwarara.Daga cikin kowane nau'in bawul ɗin da aka yanke, juriya mai gudana na bawul ɗin yanke shine mafi girma.(Matsakaicin tashar ta fi karfin azaba)
7. Tsarin ya fi rikitarwa.
8. Matsakaicin matsakaiciyar hanya ita ce hanya ɗaya.Ya kamata a tabbatar da cewa matsakaici yana gudana daga ƙasa zuwa sama, don haka matsakaici dole ne ya gudana ta hanya ɗaya.
A cikin labarin na gaba, za mu yi magana game da bawul na malam buɗe ido da kuma duba bawuloli a cikin bawuloli na maganin ruwa, waɗanda suka riga sun sami gazawa da kulawa.
